iOS webview app incorporating barcode scanner - ios

Hi I just started my adventure on IOS development and I am already stuck.
I have put together a simple webview app that is working just fine, its purpose is to load up a redeem page for certificate. I want to be able to pull the certificate information from the barcode into a text field on the page all inside the webview instead of someone having to type it in.
I have looked into multiple different threads and even a few items such as pic2go, zxing and others. However, I am still at a loss if something simple like this is possible.
Thanks for any help you can provide.

How to automatically bring the url (share-link of share api) of the corresponding app page to the clipboard when a screenshot is detected

literally, I need to know how to automatically bring the url (share-link of share api) of the corresponding app page to the clipboard when a screenshot is detected..
I'm not sure the store allow my app.. but I really want to know it is technically possible
I tried this using Android broadcast receive, and talked with many senior programmer.
But everytime I asked, they were so pessimistic.
I just know how it works in technically.

Flutter app stuck loading right after splash screen fades away

Has anybody had anything similar to this happen with a flutter app build? It works half of the time with log in credentials and when I try to use a different person it starts the loading screen and stays stuck there. I’m using firestore for the Authenticator and the database for the app.
I'm not sure what this means: "I’m using firestore for the Authenticator and the database for the app." I'm guessing you're just a bit new to firebase. Check out Net Ninja for some good starter material. You probably have logic issues in your app.
Figured it out. I was wanting to manually enter individuals login credentials from my Mac into firestorm but for some reason it wouldn't recognize it. Created a registration page within the app project and now everything works like it's suppose to.

How can I share a url from a browser to my app in iOS?

TL/DR
How can I make an iOS app appear on share sheet to receive shared urls from any other app?
This is a super newbie post as I have never really touched swift to develop anything, but I couldnt find the answer to my question on google so i wanted to start here. Almost everything I found by googling around is UIActivityViewController which appears more to be about how to share content from my app to another app; while what I am trying to do is share urls from another app to my app.
I am try to build a simple app for ios (doesnt have to be old version compatible because it will be only used by me) that can be a receiver for shared urls from apps like safari, brave or youtube. All the app does is when user clicks on the share button, and then chooses the app, the app gets the relevant data that is being passed, and then posts it to a backend server.
I can accomplish this on my android app/devices with an intent filter action android.intent.action.SEND in the manifest, and then listening for it with Intent intent = getIntent() in my method.
Would someone be kind enough to point me in the right direction at what I should look into (google about). If you can also point me to some sample code examples on how to write an app that can be the receiver for shared data (like urls), that would be fantastic. I am not sure what to search for so that my app can show up on share sheet, and how to then react with the data.
Again, apologies for the super noob question, but I couldnt translate my idea to something relevant on google.
It can be achieved by an Action Extension. Search for it.
Here is one:

I think both Share extension and Action extension can do the job. It depends on your needs.
Check this table to make sure which one is more appropriate for your purpose.
You can refer to App Extension Programming Guide by Apple.

How to work with Firebase App Indexing for IOS Apps

i am in the process of making my app with firebase i am pretty much done with that except Firebase App Indexing. I am very exited with this feature because it could help me to increase my app get more traffic from the web but the problem is i really can't able to see how to implement this. According to Firebase Docs i just need to register my app with this pice of code
[[FIRAppIndexing sharedInstance] registerApp:your Apple ID from iTunes Connect];
I have done that but what should i do after that?
1.My app is firebase app that means i don't have any website to host my content except firebase realtime database. Does my content is available for crawlers? if not how can i make available to them?
2.If i can able to show my content in the google search results i don't wanna show all the content and i wanna show just some of my content for example i have a social app for sharing General Knowledge questions, i wanna show just the question like "What is the highest mountain" in the search results and if the user want to see the answer it should take them to my app how can i do that?
3.As per docs i came to know that i need to create univiersal links for my app content to direct users from google search but how shold i do that ? Lets say should i crate universal links when the user create question?? if so how can i do that ??
Thank you very much for the help.
This is not currently possible on iOS using Firebase App Indexing. The situation is slightly different on Android, but that is not applicable to your question.
On iOS, Firebase App Indexing is simply highlighting pages on your website in Google search results that have corresponding content inside your app. This is achieved by piggybacking on Apple's Universal Links standard, and there is no proactive 'crawling' going on inside your app. This means unless you have a corresponding web page for your app with 1:1 content parity, you can't really benefit from Firebase App Indexing on iOS as it comes out-of-the-box.
The best workaround is to generate little 'placeholder pages' for every piece of content in your app, which the sole purpose of opening your app (if it is installed) or redirecting to the App Store (if it is not installed). Ideally you'll need some sort of deferred deep linking system so that users still see the correct content after downloading. Fun fact: this is essentially how HotelTonight operates their entire business model. Unfortunately Firebase's implementation is not mature enough to support this full flow, and Google hasn't quite figured out how to rank app-only content properly yet in search results so you will probably need to pro-actively submit your placeholder pages to them.
Shameless plug: at Branch, we provide all of the above as a free service. You can read more about it here and take a look at the set up docs here.

get iphone drawing into a browser

i need to build a system where our customers can sign a contract on the ipad or galaxy-tab of our employees.
i am a ruby-on-rails webdeveloper so it would be easist thing for me to do it as an onlineapplication.
big big questions is:
my guy says, his ipad has such a great function with the pen, that he can write/sign things.
is it possible to grab this input with a browser? like im making a drawing-canvas, and when the submits the form, the ipad generates it as an image and send it to the server?
otherwise i need to build up a native app. my guy wants to keep his ipad, so i get in trouble while every app needs to be downloaded by the appstore - means i cant develop him a app and only he can get it. right?
ok,
build my own formtastic input
**canvas to image** – An input plugin to use a canvas for drawings (mostly autographs). the
drawing will be submitted to the server
